Abstract

During the COVID-19 pandemic, everyone has the free opportunity to learn various things and anywhere. Therefore, this service activity provides breadth for all mathematics students/teachers/lecturers in Indonesia to learn about Mathematical Modeling using Calculus, which is assisted by the GeoGebra application. This activity is a collaboration between the Indonesian Mathematical Association (IndoMs), Program Studi Pendidikan Matematika Sanata Dharma, Program Studi Matematika Universitas Kristen Satya Wacana dan Program Studi Pendidikan Matematika Universitas Katolik Widya Mandira. Participants in this activity amounted to 62 (students, teachers and lecturers) from 15 campuses and 5 high schools spread throughout Indonesia. The objectives of this training are for participants to be able to: (1) understand the basic concepts of modeling using calculus; (2) pose everyday problems that can be modeled with calculus; (3) able to use geogebra in completing and analyzing mathematical modeling; and (4) able to communicate the results of mathematical modeling in written and oral form in a structured manner. Based on the evaluation results, this activity can be carried out well and the expected goals can be achieved.

Abstract

Mastery of mathematical concepts and skills in solving mathematical problems are basic abilities that must be possessed by mathematics teachers. Teachers must be able to provide strategies in producing solutions related to problems that become problems among students so that they are able to participate in learning activities properly. SD St. Angela Atambua is one of the education providers that wants to realize the goals of education. But in reality there are still many obstacles faced by St. Angela Elementary School teachers regarding the right strategies in overcoming students' problems, especially in concept mastery. Therefore, the service team together with the teachers of SD St. Angela Atambua tried to solve the problems of students by conducting training and mentoring in order to build a new mindset in solving every problem related to mathematics learning. The expected goal is that teachers are able to overcome the problems faced by students. The method used in this service is training and mentoring. Some of the positive things obtained from the implementation of this service include; 1) teachers are very enthusiastic in participating in activities because they get new information. 2) the service team provided assistance according to the problems experienced by the partners. 3). teachers are able to implement the concepts that have been obtained so that they can develop ideas and creativity by utilizing existing learning media as a form of solution to the problems experienced. With this math concept planting training, it is able to answer the challenges faced by partners so that students can take part in learning more enthusiastically and enthusiastically and can increase interest, motivation to learn, especially understanding of mathematical concepts to be better.

Abstract

Mathematics is studied from basic education to higher education. Understanding math concepts is important to learn because it is related to numeracy skills and also to form the basis of understanding at a higher level. One of the important materials to study is division, especially remainder division. This study aims to analyze and compare the understanding of elementary school teachers and prospective mathematics teachers in solving division problems with remainders. This research is a descriptive qualitative. Data were collected through descriptive tests and in-depth interviews with 13 elementary school teachers and 19 mathematics education study program students. The results showed that 92.3% of teachers used the porogapit method in solving the remaining division problems, and the rest used the Gasing method.  Meanwhile, 63.16% of student teachers used the porogapit method and the rest showed more method variations. Although student teachers tended to be more thorough in completing the work, errors were still found due to inaccuracy and lack of conceptual understanding. Both groups have not shown a thorough mastery of the concept of remainder division. These findings provide a basis for improving the quality of mathematics learning.

Abstract

This study aims to analyze students' understanding of the concept of composite functions in terms of VAK (Visual, Auditory, and Kinesthetic) learning styles. The type of research used is descriptive qualitative with three subjects, namely 11th grade students of SMA Katolik Giovani Kupang, selected through purposive sampling. Data were collected using concept comprehension tests, learning style questionnaires, interviews, and documentation, then analyzed using the Miles and Huberman model through the stages of data reduction, data presentation, and conclusion drawing with triangulation of techniques and sources. The results of the study indicate that students with visual, auditory, and kinesthetic learning styles are able to restate concepts. However, subjects with visual and auditory learning styles are less careful in choosing work procedures and still make mistakes in algebraic calculations. Meanwhile, students with kinesthetic learning styles demonstrate better, more structured, and procedure-compliant conceptual understanding.

Abstract

This study aims to determine the relationship between learning interest and mathematics learning outcomes of grade X students at Giovanni Catholic High School in Kupang. In reality, students' mathematics learning outcomes are still low due to low learning interest, which affects their learning achievement. This study uses a quantitative approach with a correlational method. The population in this study was all tenth-grade students at Giovanni Catholic High School in Kupang, who were selected using purposive sampling. The instruments used were a learning interest questionnaire with indicators of enjoyment, attention, interest, and involvement, as well as mid-semester summative scores (STS) in mathematics as learning outcome data. Data analysis was performed using the Shapiro–Wilk normality test and Spearman's rho correlation test with the help of SPSS Statistics 26. The results showed a positive and significant relationship between learning interest and students' mathematics learning outcomes. This means that the higher the students' learning interest, the higher the learning outcomes achieved. These findings are expected to serve as a basis for educators in designing more interesting and participatory learning strategies to increase interest and learning outcomes in mathematics.

Abstract

The Pirie-Kieren theory provides a dynamic framework that explains how mathematical understanding develops in layers, starting from initial introduction to reflection through eight layers of understanding. The eight layers of understanding are Primitive Knowing, Image Making, Image Having, Property Noticing, Formalizing, Observing, Structuring, and Inventising. This study aims to analyze students' mathematical understanding in solving literacy problems based on Pirie-Kieren's theory. This study is a qualitative descriptive study, involving 15 tenth-grade students at SMA Negeri 2 Kupang Barat, Indonesia. The research instruments used were literacy tests and interviews. In-depth interviews were conducted with student representatives who had reached each layer of understanding. Student representatives were selected based on purposive sampling. Data analysis in this study was carried out in four stages, namely data reduction, data presentation, conclusion drawing, and triangulation. The literacy test data were analyzed based on Pirie-Kieren's eight layers of understanding. The eight layers of understanding are. The results show that 73.33% of students reached the image having a layer of understanding, 13.33% reached the formalizing layer, 6.67% reached the image-making layer, and 6.67% reached only the primitive knowing layer. No students reached the observing, structuring, or inventing layers. The dominance of students in the image, having a level of understanding, shows that most students have only reached the initial stage. These results indicate that students' mathematical understanding of literacy questions remains at a basic level and has not developed into a reflective understanding.    Keywords: mathematical literacy, literacy questions, mathematical understanding, Pirie Kieren theory.
